Abstract:

The overall goal of this project is to develop a fundamental understanding of critical material interfaces in naturally occurring materials in order to provide assembly strategies for the development of high-performance functional nanocomposites. The general strategy is to study the assembly process at critical interfaces that dramatically influence the dispersion of nanofillers, the interfacial interactions between matrix and nanofiller, and ultimately the performance of nanocomposites. Specifically, our research plan is focused on the understanding of the fundamental mechanisms of self-assembly in silk biopolymers and their interfacial interactions with inorganic nanostructures. We employ fabrication techniques including layer-by-layer LbL deposition, vacuum-assisted self-assembly, and spin-assisted self-assembly, as well as patterning techniques including capillary transfer lithography and solvent-assisted micro-contact molding to create complex silk structures and nanocomposites. We demonstrated fabrication of ultrastrong and tough biographene paper with potential for conductive path writing.
